Title: Portable telephone with attached hinged flap
Inventor: HIEBEL CLAUDE
IPC: H04W88/02
Filed: 2000-01-07
Abstract: The flap movement is used to determine the operational state of the phone.  The portable radio telephone comprises a box (1) and a mobile flap (12) rotating about the corner of the box. The flap may adopt one of three positions, a folded position, an open position or an intermediate position. A detector (16) senses the position of the flap and a switch is associated with the detector. The switch acts to put the phone off-hook when the flap is open, on-hook when the flap is closed, and in hands-free mode when the flap is in the intermediate position. The hinge for the flap includes a spring and detent mechanism, defining the three rest positions of the flap.

Abstract: A gas duct includes a ceramic honeycomb structure includes a metal case, a ceramic honeycomb structure accommodated in the metal case, and a holding member placed between the outer surface of the ceramic honeycomb structure and the inner surface of the metal case. The holding member has, at the two ends, to-be-connected areas engageable to each other and is wound round the outer surface of the ceramic honeycomb structure in such a way that the to-be-connected areas of the two ends are engaged to each other and that the connected area and its vicinity face the partition wall of each cell constituting the honeycomb structure. In the gas duct, even when the ceramic honeycomb structure has thin partition walls, the honeycomb structure is not broken when it is accommodated in a metal case, i.e. during the canning.

Title: Euv condenser with non-imaging optics
Inventor: MCGUIRE JAMES P JR
IPC: H01L21/027
Filed: 2000-01-25
Abstract: An illumination system and condenser for use in photolithography in the extreme ultraviolet wavelength region having a first non-imaging optic element (14) collecting electromagnetic radiation from a source (12) and creating a desired irradiance distribution and a second non-imaging optic element (18) receiving the electromagnetic radiation from the first non-imaging optic element (14) and redirecting and imaging the electromagnetic radiation. The electromagnetic radiation emanating from the second non-imaging optic element (18) is suitable for being received by other conventional optical surfaces to provide a desired irradiance distribution with a desired angular distribution and desired shape. Facets (34) are used to provide the desired illumination over the desired illumination field. Reflective facets (34) may be placed on the second non-imaging optic, which can reduce the number of mirrors and increase efficiency. The condenser and illumination system are used in combination with a projection optic (36) to project the image of a reticle or mask (30) onto a photosensitive substrate (50), such as a semiconductor wafer used in the manufacture of electronic or semiconductor devices. The condenser of the present invention provides an efficient condenser in a compact package and provides desirable illumination properties for imaging relatively small feature sizes less than 0.13 microns.

Title: Method and apparatus for culling directly on a harvesting apparatus
Inventor: MATSON KEVIN W
IPC: A01F12/00
Filed: 1998-10-29
Abstract: A combine culling apparatus for selecting product test samples has a novel culling apparatus mounted on a known combine (10) or the like. The culling apparatus includes a collector (100), e.g., a cyclone, for receiving product, e.g., seeds, from the com-bine and a measuring compartment for receiving product from the collector.  Soybeans or other plants are arranged in a plurality of plots to be harvested.  Test samples from these plots are se-quentially collected by the apparatus.  Test data pertaining to the plants is stored on a computer system on the combine culling apparatus. Current data pertaining to a current test sam-ple, e.g., such as yield, is collected on board the combine. The computer sys-tem on the combine selects whether to discard or to save a current test sam-ple while on board the combine based on the current data and said stored test data. The method enables culling soy-bean lines and other crops directly on the combine by using a computer to calculate a check index from a set of check varieties compared to indexes of lines of interest.

Title: Dispositif a haute capacite permettant de mettre en contact une vapeur et un liquide
Inventor: BUCHANAN JOHN SCOTT
IPC: B01D3/22
Filed: 1998-11-06
Abstract: L'invention concerne un plateau permettant de mettre en contact une vapeur et un liquide. Ce plateau est utile pour la distillation, les procédés de transfert de chaleur et de transfert de masse où le liquide descend et la vapeur monte à travers le récipient. Dans le présent dispositif, la surface perforée (1, 7) du plateau est relativement réduite, de sorte que le liquide est entraîné vers le haut. Le courant liquide est amené vers le bas dans une grande zone de séparation (5). La force d'impulsion du liquide vers le bas et la grande zone de séparation (5) permettent de traiter des courants de liquide et de vapeur à débit élevé sans pour autant surcharger la capacité de séparation vapeur/liquide du dispositif. Ce dispositif comprend également des tuyaux d'évacuation (3) et des chicanes (4) servant à dévier le courant de vapeur et de liquide traversant le récipient.

IPC: B01J8/12
Filed: 1998-11-23
Abstract: A raining bed heat exchanger includes: a hollow stack; a feed inlet located near the top of the stack for introducing particulate material into the stack so that the material falls through the stack; a gas inlet located near the bottom of the stack for introducing rising gases into the stack so that the gases flow counter to the falling material; a plurality of baffles supported within the stack between the feed and gas inlets for retarding the falling material and prolonging its exposure to the gases; and a disengagement section located near the top of the stack for separating from the gases particulates entrained by the rising gases. The disengagement section includes a screen positioned within the stack and having a plurality of gaps through which the rising gases pass in order to sufficiently separate the entrained particulates. Alternatively, the disengagement section can include a filter media to separate the entrained particulates. Also, at least one of the baffles can include a hollow tube and refractory insulation surrounding the hollow tube. The heat exchanger can be connected to a cyclone to form a heat exchanger system that includes a flow generating mechanism adapted to continuously reintroduce particulates separated by the cyclone back into the heat exchanger. The invention also features a method of using a raining bed heat exchanger to efficiently preheat and partially calcine limestone before delivering the limestone to a calciner furnace.

Title: Current mode asynchronous decision a/d converter
Inventor: SEVENHANS JOANNES MATHILDA JOS
IPC: H03M1/42
Filed: 2000-08-15
Abstract: An analog-to-digital converter (ADC) for telecommunication applications such as ASDL/VDSL UMTS/GPRS wherein the conversion is realized in current mode instead of voltage mode. The power consumption is thereby reduced and the converter is adapted to be used in (low voltage) battery operated products. The structure of the converter is also simplified because summing of currents is easier than summing of voltages. The converter comprises at least a first set of N = 64 first current cells (CC) coupled in parallel between lines (L+, L-) of a differential current bus.     Each first current cell comprises a current source (ICC) to supply a first additional current (64xlref) to the current bus under control of first comparator circuits (COMP1+, COMP1-). The first comparator circuits of the current cells are coupled in cascade and activated step-by-step one after each other.      In a preferred embodiment, the converter (ADC) further includes one or more second set of N second current cells (FC) also coupled in parallel between the lines (L+, L-) of the differential current bus and similar to the first current cells. The second cells however include an amplifier (AMP2+, AMP2-) with a gain N coupled between the lines and second comparator circuits (COMP2+, COMP2-), and have a second current source (IFC) to supply a second additional current (Iref) to the current bus under control of the second comparator means. Moreover, the second current cells are activated (F2) after the operation of the first current cells of the first set is completed. The amount of hardware is thereby reduced, e.g. by factor of 2 5, as well as the cost owing to a smaller silicon area on the chip.
